Description

Technical Field

[0001] The invention relates to the technical field of vibrating feeding equipment, and in particular to a high-efficiency vibrating feeder used for concrete processing. Background Art

[0002] With the continuous development of infrastructure construction and construction industry, especially in the fields of water conservancy projects, transportation, etc., concrete vibrators are used more and more widely.

[0003] In the prior art, when using concrete, the concrete is usually poured directly into a hopper or other container to allow the concrete to flow and be transported, and the concrete is vibrated by a vibrating device before or after transportation to discharge the bubbles in the concrete. This bubble discharge method is time-consuming and labor-intensive. If a vibrating feeder is used to transport and feed the concrete, the bubbles in the concrete can be discharged by vibration during the transportation process. This bubble discharge method saves time and labor.

[0004] However, concrete will tend to liquefy under the action of vibration. Due to the different densities of aggregate and mortar, the density of aggregate is large. Under the action of vibration, aggregate will sink to the lower layer of mortar, and water will be squeezed out and rise, forming a stratified concrete structure.

[0033] An efficient vibrating feeder for concrete processing, as Figure 1-Figure 4As shown, it includes a vibrating hopper 1 and a diffusion mechanism for evenly distributing aggregates. The diffusion mechanism includes a distribution frame 201. Two groups of distribution frames 201 are symmetrically arranged in the vibrating hopper 1, and each group has three distribution frames. Four evenly distributed sealing plates 202 are slidably connected in the distribution frame 201. One side of the four sealing plates 202 is fixedly connected with a distribution rod 203. When the distribution rod 203 moves, the aggregate in the mortar can be lifted. One end of the distribution rod 203 is slidably connected to the inner wall of the distribution frame 201. The vibrating hopper 1 is provided with a changing mechanism for changing the movement trajectory of the distribution frame 201. The changing mechanism can make it easier for the distribution frame 201 to sink into the concrete.

[0034] like Figure 3-Figure 5 As shown, the diffusion mechanism also includes a horizontal plate 301, a horizontal plate 301 is arranged on the lower side of the material distribution frame 201, a first elastic member is arranged between the horizontal plate 301 and the material distribution frame 201, and the first elastic member is a tension spring. Two groups of guide frames 302 are symmetrically fixed on the horizontal plate 301, each group has two, and each group of guide frames 302 are symmetrically arranged. Four evenly distributed special-shaped grooves are opened through the outer wall of the material distribution frame 201, and the four guide frames 302 are arranged one by one corresponding to the four special-shaped grooves. The four guide frames 302 are respectively clamped. The guide blocks 303 are obliquely slidably connected to the four guide frames 302, a second elastic member is arranged between the guide blocks 303 and the guide frames 302, and the second elastic member is a compression spring. The four special-shaped grooves are slidably connected with sliders 304, the slider 304 is fixedly connected to the sealing plate 202, and a third elastic member is arranged between the slider and the special-shaped groove, and the third elastic member is a compression spring. A convex shaft 305 used in conjunction with the guide block 303 is fixedly connected to one side of the slider 304.

[0035] like Figure 5 As shown, the diffusion mechanism also includes a limiting plate 401, the limiting plate 401 is hinged on the guide block 303, a fourth elastic member is arranged between the limiting plate 401 and the guide block 303, the fourth elastic member is a torsion spring, and the convex shaft 305 is used in conjunction with the limiting plate 401.

[0036] like Figure 3 and Figure 6As shown in the figure, it further includes a lifting mechanism. The lifting mechanism includes a special-shaped frame 501. Two groups of special-shaped frames 501 are slidably connected through the vibrating hopper 1 in a penetrating manner, with three in each group. The special-shaped frames 501 are arranged in one-to-one correspondence with the cloth racks 201. At the bottom of one side of the special-shaped frame 501, an installation box 502 is fixedly connected. A first elastic wedge block 503 is slidably connected in the installation box 502. Three guide boxes 504 are fixedly connected to the bottom of the vibrating hopper 1. Two adjacent special-shaped frames 501 are located in the corresponding guide boxes 504. A rectangular pipe 505 is horizontally slidably connected in the guide box 504. The lower parts of two adjacent special-shaped frames 501 are located in the corresponding rectangular pipe 505. A number of locking grooves for cooperating with the first elastic wedge block 503 are provided in the rectangular pipe 505. C-shaped frames 506 are symmetrically and horizontally slidably connected to the special-shaped frame 501. A connecting plate 507 is hinged to one side of the C-shaped frame 506. The upper part of one side of the connecting plate 507 is rotatably connected to the cloth rack 201.

[0037] As Figure 2 , Figure 7-Figure 8 shown in the figure, the direction-changing mechanism includes a horizontal shaft 601. A horizontal shaft 601 is rotatably connected through each group of cloth racks 201 in a penetrating manner. C-shaped rods 602 are fixedly connected to both ends of the horizontal shaft 601. Protruding shafts 603 are fixedly connected to both sides of the C-shaped rod 602. Sliding boxes 6031 are symmetrically and fixedly connected to both sides of the vibrating hopper 1. A sliding seat 604 is vertically slidably connected in the sliding box 6031. A fifth elastic member is provided between the sliding seat 604 and the inner wall of the sliding box 6031. The fifth elastic member is a tension spring. Wedge plates 605 for cooperating with the protruding shafts 603 are symmetrically hinged in the sliding seat 604. The protruding shaft 603 can drive the sliding seat 604 to slide through the wedge plate 605. A sixth elastic member is provided between the wedge plate 605 and the sliding seat 604. The sixth elastic member is a compression spring.

[0038] As Figure 7-Figure 8 shown in the figure, the direction-changing mechanism further includes a second elastic wedge block 701. Second elastic wedge blocks 701 are symmetrically and fixedly connected to the inner wall of the sliding box 6031. The verticality of the lower inclined surface of the second elastic wedge block 701 is greater than that of the upper inclined surface. The second elastic wedge block 701 is used in cooperation with the protruding shaft 603.

[0039] As Figure 7 shown in the figure, the direction-changing mechanism further includes a one-way damping strip 801. One-way damping strips 801 are symmetrically and fixedly connected to the inner wall of the sliding box 6031. The one-way damping strip 801 is used in cooperation with the protruding shaft 603. When the protruding shaft 603 slides upward, the one-way damping strip 801 does not apply damping to the protruding shaft 603.

[0040] As Figure 6As shown, it also includes a first magnet 901, the first magnet 901 is fixedly connected inside the special-shaped frame 501, and the second magnet 902 is fixedly connected to the top of the rectangular tube 505. The first magnet 901 and the second magnet 902 repel each other, and the rectangular tube 505 can slide horizontally through the repulsion between the first magnet 901 and the second magnet 902.

[0041] like Figure 1 and Fig. 9 As shown, a baffle 1001 is also included. The baffle 1001 is fixedly connected in the vibrating hopper 1. The special-shaped frame 501 is slidably connected with the baffle 1001 through-type. The top surface of the baffle 1001 is a horizontal plane. When the concrete flows through the baffle 1001, the flow speed can be slowed down.

[0042] Initially, two adjacent cloth racks 201 are on the same horizontal plane. The outer wall of the rectangular pipe 505 is in contact with the rear inner wall of the corresponding guide box 504. The first elastic wedge block 503 at the front is inserted into the locking groove of the corresponding rectangular pipe 505, and there is a gap between the first elastic wedge block 503 at the rear and the locking groove of the corresponding rectangular pipe 505. First, pour the concrete into the vibrating hopper 1 and start the vibrating hopper 1. The vibrating hopper 1 starts to vibrate at a high frequency to convey the concrete. The air bubbles in the concrete rise and are discharged after being affected by the high-frequency vibration. Subsequently, the concrete flows along the surface of the vibrating hopper 1. The aggregates in the concrete settle to the lower layer of the mortar under the influence of the high-frequency vibration. Since the vibrating hopper 1 generates an up-and-down acting force when vibrating, the special-shaped frame 501 is affected by the vibration and generates an upward force, and drives the corresponding cloth rack 201 to lift upward through the U-shaped frame 506 and the connecting plate 507, and also drives the mounting box 502 to lift upward. The mounting box 502 drives the first elastic wedge block 503 to lift upward. After the first elastic wedge block 503 at the front lifts upward, it squeezes against the locking groove in the corresponding rectangular pipe 505. It should be noted that since the rectangular pipe 505 is relatively heavy, when the first elastic wedge block 503 squeezes against the locking groove in the rectangular pipe 505, the rectangular pipe 505 will not slide. The inclined surface of the first elastic wedge block 503 at the front is stressed and contracts and slides, and after lifting, it is released and inserted into the next locking groove, and its bottom surface contacts the horizontal plane of the locking groove. The first elastic wedge block 503 is restricted from descending, so that the corresponding special-shaped frame 501 and the cloth rack 201 remain stable after lifting. Since there is a gap between the first elastic wedge block 503 at the rear and the locking groove of the corresponding rectangular pipe 505, the first elastic wedge block 503 at the rear cannot contact the locking groove after lifting, so that only slight undulations can occur in the special-shaped frame 501 and the U-shaped frame 506 at the rear. Thus, the cloth rack 201 and the special-shaped frame 501 at the front can be continuously lifted upward, while the cloth rack 201 and the special-shaped frame 501 at the rear maintain a stable height. Subsequently, the concrete flows to the cloth rack 201 at the front. Since the aggregates in the concrete settle to the lower layer of the mortar after being vibrated, when the cloth rack 201 lifts, it drives the four cloth rods 203 inside it to lift upward. The four cloth rods 203 lift upward and push the aggregates in the mortar upward. And the cloth rack 201 pulls the cross plate 301 upward through the first elastic member. Since the vibrating hopper 1 vibrates up and down and has a high vibration frequency, the cloth rack 201 quickly lifts upward. At this time, the cross plate 301 is immersed in the concrete, and the concrete is relatively viscous. When the cross plate 301 lifts upward, it is subject to resistance, and the rising speed of the cloth rack 201 is relatively fast. The first elastic member is stressed and extended in a short time. The cross plate 301 drives the corresponding four guide frames 302 to descend relative to the cloth rack 201. The four guide frames 302 drive the guide blocks 303 on them to squeeze against the corresponding convex shafts 305. The convex shafts 305 are stressed and drive the corresponding cloth rods 203 to slide horizontally through the sliders 304 and the sealing plate 202.After the sealing plate 202 slides, it always blocks the special-shaped groove corresponding to it, thereby preventing concrete from entering the special-shaped groove. At the same time, the third elastic member is forced to shrink, and the placing rod 203 slides horizontally. After the placing rod 203 slides, the gap between it and the placing frame 201 increases, so that part of the aggregate falls through the placing rod 203, and the remaining aggregate continues to stay on the upper side of the placing rod 203 and is driven by the placing rod 203 to lift upward, and then the convex shaft 305 slides until it contacts the limiting plate 401, and the limiting plate 401 cannot rotate. The convex shaft 305 slides along the inclined surface of the limiting plate 401 and passes over it. At this time, the third elastic member is released to drive the slider 304 to slide and reset. The slider 304 drives the convex shaft 305 to slide and reset, and drives the placing rod 203 to slide and reset through the sealing plate 202. At this time, the first elastic member slowly shrinks and drives the cross plate 301 to lift upward, and the cross plate 301 drives the four guide frames 302 thereon to lift upward , the guide frame 302 drives the guide block 303 therein to lift upward. Since the elastic force of the second elastic member is less than the elastic force of the third elastic member, the upper inclined surface of the guide block 303 contacts and squeezes the convex shaft 305 at this time, and the guide block 303 is forced to slide obliquely downward, and the second elastic member is forced to shrink. When the limit plate 401 contacts the convex shaft 305, the convex shaft 305 squeezes the limit plate 401, and the limit plate 401 is forced to rotate with the connection point of the guide block 303 as the center. The fourth elastic member is forced to shrink until the convex shaft 305 passes over the limit plate 401. The fourth elastic member is released to drive the limit plate 401 to rotate and reset, thereby completing the distribution frame 201 and the distribution rod 203 to drive the aggregate in the mortar to lift upward, and a small part of the aggregate falls to the lower side of the distribution rod 203 through the distribution rod 203, and most of the aggregate is pushed upward by the distribution rod 203. Then repeat the above steps, the aggregate can be evenly distributed in the concrete. ,

[0043] As the aggregate is pushed upward by the distribution rod 203, the aggregate will stagnate briefly compared to the mortar. When the concrete flows to the distribution rack 201, the concrete is located on the upper side of the spoiler 1001, and the surface of the spoiler 1001 is horizontal. When the concrete flows onto the spoiler 1001, the flow speed will slow down. After a brief stagnation, the aggregate can quickly continue to flow with the mortar, thereby effectively preventing the serious misalignment of the aggregate and the mortar, resulting in uneven mixing of the aggregate and the mortar.

[0044] Initially, the protruding shaft 603 is snapped into the lower sides of the corresponding two wedge-shaped plates 605. While the fabric rack 201 rises, it drives the corresponding two U-shaped rods 602 to lift upward through the horizontal shaft 601. The U-shaped rods 602 slide upward within the sliding box 6031 and drive the protruding shaft 603 to lift upward. The protruding shaft 603 contacts and presses against the lower inclined surfaces of the corresponding two wedge-shaped plates 605. Due to the relatively large elastic force of the sixth elastic member, the wedge-shaped plates 605 cannot rotate after being pressed, and drive the sliding seat 604 to lift upward. The fifth elastic member between the sliding seat 604 and the sliding box 6031 is stressed and extends. When the sliding seat 604 is lifted to contact the lower inclined surface of the second elastic wedge-shaped block 701 and presses against the lower inclined surface of the second elastic wedge-shaped block 701, the second elastic wedge-shaped block 701 contracts and slides under the force until the sliding seat 604 passes over the second elastic wedge-shaped block 701. The second elastic wedge-shaped block 701 releases and slides back to its original position. Subsequently, the sliding seat 604 contacts the bottom of the one-way damping strip 801, and the one-way damping strip 801 blocks the sliding seat 604, making the sliding seat 604 unable to lift upward. At this time, after the protruding shaft 603 continues to lift, the pressing force on the lower inclined surface of the wedge-shaped plate 605 increases. The wedge-shaped plate 605 rotates around the connection point with the sliding seat 604 under the force, and the sixth elastic member is stressed and contracts. After the protruding shaft 603 continues to lift and passes over the wedge-shaped plate 605 and no longer contacts the wedge-shaped plate 605, the sixth elastic member contracts and drives the wedge-shaped plate 605 to rotate back to its original position. After the wedge-shaped plate 605 is released from the restriction, the sliding seat 604 can move. The fifth elastic member contracts and drives the sliding seat 604 to descend. After the sliding seat 604 descends, it contacts and presses against the upper inclined surface of the second elastic wedge-shaped block 701. Due to the angle limitation of the upper inclined surface of the second elastic wedge-shaped block 701, the pressing force applied by the sliding seat 604 to the second elastic wedge-shaped block 701 is not sufficient to cause the second elastic wedge-shaped block 701 to contract, thereby keeping the sliding seat 604 stable. After the protruding shaft 603 continues to lift, it contacts the surface of the one-way damping strip 801. Due to the characteristics of the one-way damping strip 801, when the protruding shaft 603 contacts the surface of the one-way damping strip 801 and lifts upward, the one-way damping strip 801 will not apply damping to the protruding shaft 603, and the protruding shaft 603 can slide smoothly. At this time, the front fabric rack 201, the fabric rod 203 and the special-shaped frame 501 continue to lift upward until the first magnet 901 on the special-shaped frame 501 is lifted to one side of the second magnet 902. The first magnet 901 generates a repulsive force on the second magnet 902, thereby driving the rectangular tube 505 to slide horizontally. After the rectangular tube 505 slides horizontally, the lock groove on its inner front side moves away from the front first elastic wedge-shaped block 503. After the first elastic wedge-shaped block 503 is released from the restriction, it no longer restricts the height of the special-shaped frame 501, thereby enabling the special-shaped frame 501 to descend. At the same time, the lock groove on the inner rear side of the rectangular tube 505 contacts the rear first elastic wedge-shaped block 503. After the rear first elastic wedge-shaped block 503 lifts upward, it presses against the lock groove within the rectangular tube 505. The inclined surface of the rear first elastic wedge-shaped block 503 is stressed and contracts and slides,After being lifted, it is released and snapped into the next locking groove, thereby causing the rear fabric rack 201 and the special-shaped rack 501 to be lifted upward. Then, repeat the above steps to achieve the same effect, enabling the front and rear fabric racks 201 and the fabric rods 203 to work alternately, improving work efficiency.

[0045] When the front special-shaped rack 501 is no longer restricted and starts to descend, the two corresponding C-shaped rods 602 descend under their own weight. The C-shaped rod 602 drives the protruding shaft 603 to descend. At this time, the one-way damping strip 801 applies damping to the protruding shaft 603, causing the C-shaped rod 602 and the protruding shaft 603 to descend more slowly than the special-shaped rack 501. At this time, the two front C-shaped rods 602 pull the front fabric rack 201 through the cross shaft 601. The fabric rack 201 rotates around the connection point of the connecting plate 507 under the force, and pulls the C-shaped frame 506 to slide horizontally on the special-shaped rack 501 through the connecting plate 507, finally making the fabric rack 201 tend to be vertical. After the fabric rack 201 descends, it is obliquely inserted into the concrete, thereby reducing the resistance exerted by the concrete on the fabric rack 201 when the fabric rack 201 descends. Subsequently, the protruding shaft 603 slides out of the one-way damping strip 801 and contacts and presses against the upper inclined surface of the wedge plate 605. The wedge plate 605 rotates around the connection point of the sliding seat 604 under the force, and the sixth elastic member contracts. After the protruding shaft 603 continues to descend, it passes over the wedge plate 605 and contacts and presses against the sliding seat 604. The release of the sixth elastic member drives the wedge plate 605 to rotate and reset. At this time, the force exerted by the sliding seat 604 on the second elastic wedge block 701 through the extrusion force of the protruding shaft 603 increases. The second elastic wedge block 701 contracts and slides under the force. After the sliding seat 604 continues to slide, it no longer contacts the second elastic wedge block 701 and passes over it. After the second elastic wedge block 701 is released from the restriction, it resets. At this time, the fifth elastic member contracts to make the sliding seat 604 quickly descend and reset. The sliding seat 604 presses against the protruding shaft 603 through the wedge plate 605, causing the protruding shaft 603 to drive the cross shaft 601 to quickly descend through the C-shaped rod 602. The cross shaft 601 drives the fabric rack 201 to descend. The fabric rack 201 drives the C-shaped frame 506 to slide horizontally on the special-shaped rack 501 through the connecting plate 507. The fabric rack 201 rotates around the connection point of the connecting plate 507 until the fabric rack 201 forms a horizontal state, thus completing the reset of the front fabric rack 201. By making the fabric rack 201 tend to be vertical, the resistance exerted by the concrete on the fabric rack 201 can be greatly reduced, and the aggregate in the concrete can be prevented from being located under the fabric rack 201, making it impossible for the fabric rack 201 to reset. Embodiment 2

[0046] As Figure 10-11As shown, it also includes a mounting frame 1101, the mounting frame 1101 is fixedly connected to the vibrating hopper 1, an electric push rod 1102 is installed in the mounting frame 1101, the telescopic end of the electric push rod 1102 is fixedly connected to a guide plate 1103, one side of the guide plate 1103 is provided with two groups of variable pitch grooves about the middle part, each group has four, and the inclination angle of each group of variable pitch grooves gradually increases, a sliding frame 1104 is fixedly connected in the vibrating hopper 1, and eight shifting rods 1105 are slidably connected in the sliding frame 1104, and one end of the eight shifting rods 1105 are all inserted into the corresponding variable pitch grooves and slide in the variable pitch grooves.

[0047] When the concrete flows to the lever 1105, the electric push rod 1102 is started, and the telescopic end of the electric push rod 1102 is continuously extended and retracted, so that the guide plate 1103 is reciprocated and lifted, and the guide plate 1103 squeezes the lever 1105 through the variable pitch groove thereon, so that the eight levers 1105 are continuously expanded and contracted, and the eight levers 1105 stir the concrete to make the aggregate in the concrete more evenly dispersed, and then the concrete is fed through the vibrating hopper 1. The concrete passing through the vibrating hopper 1 not only completes the elimination of bubbles, but also the aggregate inside can be evenly distributed, so that the quality of the concrete is improved.

A high-efficiency vibrating feeder for concrete processing, comprising a vibrating hopper (1), characterized in that: It further includes a diffusion mechanism for evenly distributing the aggregate. The diffusion mechanism includes a cloth rack (201). Two groups of the cloth racks (201) are symmetrically arranged in the vibrating hopper (1). A number of evenly distributed sealing plates (202) are slidably connected in the cloth rack (201). One side of each of the number of sealing plates (202) is fixedly connected with a cloth rod (203). One end of the cloth rod (203) is slidably connected to the inner wall of the cloth rack (201). A direction-changing mechanism for changing the movement track of the cloth rack (201) is arranged on the vibrating hopper (1); The diffusion mechanism further includes a cross plate (301). The cross plate (301) is arranged below the cloth rack (201). A first elastic member is arranged between the cross plate (301) and the cloth rack (201). Two groups of guide frames (302) are symmetrically and fixedly connected to the cross plate (301). A number of evenly distributed special-shaped grooves are formed in a penetrating manner on the outer wall of the cloth rack (201). Each of the number of guide frames (302) is inserted into and slidable in the number of special-shaped grooves. A guide block (303) is slidably connected in each of the number of guide frames (302). A second elastic member is arranged between the guide block (303) and the guide frame (302). A slider (304) is slidably connected in each of the number of special-shaped grooves. The slider (304) is fixedly connected with the sealing plate (202), and a third elastic member is arranged between the slider (304) and the special-shaped groove. A convex shaft (305) used in cooperation with the guide block (303) is fixedly connected to one side of the slider (304); It further includes a lifting mechanism. The lifting mechanism includes a special-shaped frame (501). Two groups of the special-shaped frames (501) are slidably connected in a penetrating manner on the vibrating hopper (1). An installation box (502) is fixedly connected to one side of the special-shaped frame (501). A first elastic wedge block (503) is slidably connected in the installation box (502). Three guide boxes (504) are fixedly connected to the bottom of the vibrating hopper (1). A rectangular pipe (505) is slidably connected in the guide box (504). A number of locking grooves used in cooperation with the first elastic wedge block (503) are formed in the rectangular pipe (505). A C-shaped frame (506) is symmetrically slidably connected to the special-shaped frame (501). One side of the C-shaped frame (506) is hinged with a connecting plate (507). The upper part of one side of the connecting plate (507) is rotatably connected to the cloth rack (201); It further includes a first magnet (901). The first magnet (901) is fixedly connected in the special-shaped frame (501). A second magnet (902) is fixedly connected to the top of the rectangular pipe (505); The first magnet (901) on the special-shaped frame (501) is lifted to one side of the second magnet (902). The first magnet (901) generates a repulsive force on the second magnet (902), thereby causing the second magnet (902) to drive the rectangular tube (505) to slide horizontally. After the rectangular tube (505) slides horizontally, the locking groove on its inner front side moves away from the first elastic wedge block (503) on the front side. After the first elastic wedge block (503) is released from the restriction, it no longer restricts the height of the special-shaped frame (501), so that the special-shaped frame (501) can descend. At the same time, the locking groove on the inner rear side of the rectangular tube (505) contacts the first elastic wedge block (503) on the rear side. After the first elastic wedge block (503) on the rear side is lifted upward, it is squeezed against the locking groove in the rectangular tube (505). The inclined surface of the first elastic wedge block (503) on the rear side contracts and slides under force, and after being lifted, it is released and snapped into the next locking groove, so that the cloth rack (201) on the rear side and the special-shaped frame (501) are lifted upward. By repeating the above steps, the same effect is achieved, enabling the cloth racks (201) on the front and rear sides and the cloth rods (203) to work alternately, improving work efficiency.

2. The high-efficiency vibrating feeder for concrete processing according to claim 1, characterized in that: The diffusion mechanism further includes a limiting plate (401). The limiting plate (401) is hinged to the guiding block (303). A fourth elastic member is provided between the limiting plate (401) and the guiding block (303). The convex shaft (305) is used in cooperation with the limiting plate (401).

3. The high-efficiency vibrating feeder for concrete processing according to claim 1, characterized in that: The direction-changing mechanism includes a horizontal shaft (601). The horizontal shaft (601) is rotatably connected through each cloth rack (201). At both ends of the horizontal shaft (601), there are fixedly connected U-shaped rods (602). On both sides of the U-shaped rods (602), there are fixedly connected protruding shafts (603). On both sides of the vibrating hopper (1), there are symmetrically fixedly connected sliding boxes (6031). A sliding seat (604) is slidably connected in the sliding box (6031). A fifth elastic member is provided between the sliding seat (604) and the inner wall of the sliding box (6031). Wedge plates (605) used in cooperation with the protruding shafts (603) are symmetrically hinged in the sliding seat (604). A sixth elastic member is provided between the wedge plates (605) and the sliding seat (604); The direction-changing mechanism further includes second elastic wedge blocks (701). The second elastic wedge blocks (701) are symmetrically fixedly connected to the inner wall of the sliding box (6031). The second elastic wedge blocks (701) are used in cooperation with the protruding shafts (603); The direction-changing mechanism further includes one-way damping strips (801). The one-way damping strips (801) are symmetrically fixedly connected to the inner wall of the sliding box (6031). The one-way damping strips (801) are used in cooperation with the protruding shafts (603); Initially, the protruding shaft (603) is snapped into the lower sides of the corresponding two wedge plates (605). While the fabric rack (201) rises, it drives the corresponding two U-shaped rods (602) to lift upward through the cross shaft (601). The U-shaped rods (602) slide upward in the sliding box (6031) and drive the protruding shaft (603) to lift upward. The protruding shaft (603) contacts and presses against the lower inclined surfaces of the corresponding two wedge plates (605). Due to the relatively large elastic force of the sixth elastic member, the wedge plates (605) cannot rotate after being pressed, and drive the sliding seat (604) to lift upward. The fifth elastic member between the sliding seat (604) and the sliding box (6031) is stressed and extended. When the sliding seat (604) rises to contact the lower inclined surface of the second elastic wedge block (701) and presses against the lower inclined surface of the second elastic wedge block (701), the second elastic wedge block (701) contracts and slides under the force until the sliding seat (604) crosses the second elastic wedge block (701), and the second elastic wedge block (701) releases and slides back to its original position. Subsequently, the sliding seat (604) contacts the bottom of the one-way damping strip (801), and the one-way damping strip (801) blocks the sliding seat (604), making the sliding seat (604) unable to lift upward. At this time, after the protruding shaft (603) continues to lift, the pressing force on the lower inclined surface of the wedge plate (605) increases. The wedge plate (605) rotates with the connection point of the sliding seat (604) as the center under the force, and the sixth elastic member is stressed and contracts. After the protruding shaft (603) continues to lift and crosses the wedge plate (605) and no longer contacts the wedge plate (605), the sixth elastic member contracts and drives the wedge plate (605) to rotate back to its original position. After the wedge plate (605) is released from the restriction, the sliding seat (604) can move. The fifth elastic member contracts and drives the sliding seat (604) to descend. After the sliding seat (604) descends, it contacts and presses against the upper inclined surface of the second elastic wedge block (701). Due to the angle limitation of the upper inclined surface of the second elastic wedge block (701), the pressing force applied by the sliding seat (604) to the second elastic wedge block (701) is not sufficient to cause the second elastic wedge block (701) to contract, thereby keeping the sliding seat (604) stable. After the protruding shaft (603) continues to lift, it contacts the surface of the one-way damping strip (801). Due to the characteristics of the one-way damping strip (801), when the protruding shaft (603) contacts the surface of the one-way damping strip (801) and lifts upward, the one-way damping strip (801) does not apply damping to the protruding shaft (603), and the protruding shaft (603) can slide smoothly.

4. The high-efficiency vibrating feeder for concrete processing according to claim 1, characterized in that: It further includes a flow blocking plate (1001), the flow blocking plate (1001) is fixedly connected inside the vibrating hopper (1), and the special-shaped frame (501) is slidably connected to the flow blocking plate (1001) in a penetrating manner.

5. The high-efficiency vibrating feeder for concrete processing according to claim 4, characterized in that: The vibrating hopper (1) further comprises a mounting frame (1101), the mounting frame (1101) being fixedly connected to the vibrating hopper (1), an electric push rod (1102) being installed in the mounting frame (1101), a guide plate (1103) being fixedly connected to the telescopic end of the electric push rod (1102), two groups of variable pitch grooves being provided on one side of the guide plate (1103) about the middle part, a sliding frame (1104) being fixedly connected in the vibrating hopper (1), a plurality of shifting rods (1105) being slidably connected in the sliding frame (1104), one end of each of the plurality of shifting rods (1105) being inserted into the two groups of variable pitch grooves and sliding in the variable pitch grooves.
